These include a lecture given at Barts, explaining exactly how Ampyra works at the cell level.
My own experience on the drug is, as best I can describe it, that my muscles are working better. My physio has said that my quads and glutimus maximus muscles are not fatiguing so quickly when she exercises them.
Basically my problems with walking are that the muscles lifting my legs get tired so quickly that I can only walk a very short distance. This is still true on Ampyra, but the distance is now 300 metres, rather than 100 metres. I’m still improving and I’m a ridiculously optimistic person, so I’m hoping I’m going to get to half a mile or something like that so that I could go back to being like a person without MS! Well you never know, do you?
